The Order Batrchoidiformes (Frogfishes) contains just one family (Batrachoididae) in Australia of which there are 8 species in Australia. In Sydney we see the Eastern Frogfish (Batrachomoeus Dubius) regularly. Frogfishes are usually spotted on the sandy floor and are unmistakable with their big lips and large round heads. They have eyes much like marbles and whiskers on their chin. Fun facts; the three spines at the start of their dorsal fin are venomous, and this order of fish got their name from the loud croaking sound they can produce from their swim bladder.
